NONE of them are oxidising agents, they are reducing in stead: Silver is the best reductor, lead the weakest of this trio.
All metals are reducing (donating electrons), they are able to BE oxidised by an OXIDising agent (acceptor of electrons), like O2.
No, the 1959 nickel is not made of silver. Nickels minted in 1959 and thereafter are composed of a copper-nickel alloy (75% copper and 25% nickel). Silver was phased out of the composition in 1946.
Yes. German silver is primarily copper, though. The alloy is approximately 60% copper, 20% nickel and 20% zinc.
Not even close, Nickel "silver" has no silver and is a copper alloy. It simply looks slightly like silver. Items might be silver plated though. Nickel silver, also called German silver, is an alloy of approximately 60% copper, 20% nickel and 20% zinc; it doesn't contain any silver. The nickel gives it a shiny, silver appearance.
No, nickel silver and sterling silver are not the same value. Sterling silver is a precious metal composed of 92.5% silver, while nickel silver is an alloy of nickel, copper, and zinc that does not contain any silver. Sterling silver is typically more valuable than nickel silver.
Yes, a 1946 nickel does contain silver. Nickels minted from 1942-1945 were made with a composition of 35% silver and 56% copper, due to the wartime need for nickel. After 1945, nickel composition returned to the standard 75% copper and 25% nickel.
The metals silver, copper and nickel are elements. It is brass that is an alloy, and copper and zinc are what make it up.

...If it is nickel silver it contains no silver. It is rather an alloy of nickel and copper to create the look of silver.
Nickel silver is a type of alloy made from copper, nickel, and zinc, but it does not contain any silver. It is not magnetic because none of the metals it is composed of—copper, nickel, and zinc—are magnetic in their pure form.
No it is made from an alloy of copper and nickel.
Yes, a 1946 nickel does contain silver. Nickels minted from 1942-1945 were made with a composition of 35% silver and 56% copper, due to the wartime need for nickel. After 1945, nickel composition returned to the standard 75% copper and 25% nickel.
It isn't silver. Nickel "silver" refers to an alloy of copper with nickel and zinc to make it look like silver but it really contains no silver at all.
No, they don't. US nickels are made of copper and nickel. The only ones that DO contain silver are war nickels, minted 1942-1945.
U.S. coins used to be made with silver, typically a blend of 90% silver with 10% copper. Then modern dimes, quarters, and half dollars are nickel-coated copper. Nickels are made with 25% nickel and 75% copper. There aren't any coins made of a silver/nickel blend.
